o really? i didnt say ported now did i?
VENTED is slots that run inside the box to more less make the box work
BANDPASS is cheap crapy thing ordered off ebay, easy to blow subs and not as easy to note distortion to tune properly.
vented - what you cant see is the vents follow along the side and 1/2 across the back off the box
bandpass - note the holes. siqqqq
